My said invention relates to improvements in toy drums designed forchildrens use and aims to provide an improved drum of this characterwhich can be manufactured at an extremely low cost, both as to materialsand workmanship, and further to provide a drum which will have theappearance and action of the customary drum and which will be strong anddurable in use.

With said objects in view the invention includes the novel constructionhereinafter de scribed, the invention being defined by the claimsappended hereto.

In order that the invention may be more readily understood reference ismade to the accompanying drawings in which Figurel is a side elevationof the drum with a part broken away to show it in section, and

Fig. 2 is a enlarged sectional detail through one of the corners,

Fig. 3 is a sectional view of the sheet metal cylinder at thecommencement of the drum forming operation,

Fig. l is a view illustrating how the cylinder appears after theenlarged ends have been formed therein,

Fig. 5 is a view showing the next stage of operation in forming theshoulder of re-entrant or channel shape, and

Fig. 6 is a view showing the head in position and how the parts appearprior to overturning the outer cylinder end..

Fig. 7 is a detail of one of the drum heads, partly in section.

In proceeding to construct my novel drum I provide a cylinder ofinflexible ductile material (metal) indicated at 1 in Fig. 8. By

means of a suitable press I enlarge the ends of this so as to provideend cylindrical portions 1a and annular outwardly facing shoulders 11)(F i 4). These shoulders serve to support and hold (as hereinafterdescribed) the margins of the drum heads, and for more secure retentionI prefer to depress them to form annular channels, conveniently bypressing until the shoulder forming portions incline outwardly anddownwardly as shown in Fig. 5.

Thereafter I supply a pair of disks 2 of 1930. Serial No. 434,287.

flexible material such as strong paper having upstanding peripheralflanges 2a and place t iese within the enlarged ends of the drumcylinder with the margins of the disk overlying the channeled shouldersand the peripheral flanges juxtaposed to the inner walls of the enlargedcylinder portions. I then place within the enlarged portions injuxtaposition to the inner faces of the peripheral flanges of the headsrings 3 of inflexible ma terial such as stifl' cardboard or paste board,whereafter by the use of a suitable press or die I roll or bend theouter edges of the cylindrical portions la over upon the outer edges ofthe rings as indicated at 10 which forces them inward and causes theirlower edges to clamp the margins of the heads against the channeledshoulders thereby holding the heads in position. The forcing of themargins down into the channels places the disks 2 under tension.

After the drum is complete the heads are covered with a moisture proofcoating, and of course the cylinder or body may be painted or ornamentedas desired.

The result is a drum which can be manufactured at an extremely low costdue to the few number of parts employed, the cheapness of material, andthe economical manner of assembly.

I claim:

1. A toy drum comprising a cylindrical body having enlarged integral endportions with outwardly facing annular channels at the inner ends ofsaid enlarged portions, disks of flexible material having their marginsoverlying said channels, rings within said enlarged ends and engagingsaid disk margins, and means for holding said rings with their inneredges pressed against the disk margins to clamp them in said channels.

2. A toy drum comprising a cylindrical body having enlarged integral endportions with outwardly facing annular channels at the inner ends ofsaid enlarged portions, 95 disks of flexible material having theirmargins overlying said channels, rings within said enlarged ends andengaging said disk margins, said enlarged portions having their outeredges overturned upon the outer edges of the rings and holding them withtheir inner edges clamping the disk margins in said channels.

3. A toy drum according to claim 1 in which the channels are formed byoutwardly and downwardly inclined portions of the cylinder.

4. A toy drum comprising a cylinder of inflexible material havingenlarged ends and 19 annular outwardly facing shoulders at the innerends of said enlarged ends, heads of flexible material having marginalportions overlying said shoulders and peripheral cylindrical portionsjuxtaposed to the inner walls of said enlarged portions, rings ofinflexible material lying within said cylindrical portions of the heads,and means for clamping said rings in position.

5. A toy drum comprising a cylinder of inflexible material havingenlarged ends and annular outwardly facing shoulders at the inner endsof said enlarged ends, heads of flexible material having marginalportions overlying said shoulders and peripheral cylindrical portionsjuxtaposed to the inner walls of said enlarged portions, rings ofinflexible material lying within said cylindrical portions of the heads,said enlarged portions having their outer ends overturned upon the outerfaces of said rings.

In testimony whereof I aflix my signature.
